2. Install a plastic bellcrank on the right motor strut post
extending below the bottom of the bottom wing, using a
plastic standoff and 2mm x 8mm wood screw. If required,
enlarge the hole in the bellcrank with a 5/64" [2mm] drill bit
so that the screw slides freely into the hole.
Install the bellcrank with the flange on the plastic standoff
against the wing. The long arm of the bellcrank should face
forward and the short arm should face the wing tip. Do not
install the screw until the next step.

short arm of the bellcrank to the aileron control horn. The

Install the 2mm x 8mm screw on the bellcrank. Do not
overtighten the screw.

not install the screw holding the servo horn to the servo until
the next step.
